loss?
Answers
Answer:
Step-by-step explanation:
CP=44kg
P% of one part =14%
L% of other part =8%
Total loss% =4%
SP at 8%=?
now,
CP-x=14%
44-14/100=x
4,400-14=100x
4,386=100x
x=43.86
now,
l%=CP-SP/CP*100%
4%=44-SP/44*100%
176=44-100SP
100SP=-132
SP=Rs.0.75
now,
SP at 8% loss=?
l%=CP-SP/CP*100%
8%=CP-0.75/CP*100%
8CP=100CP-75
75=92CP
CP=Rs.0.81........
The quantity sold at loss is 36 kg.
Given - Total quantity, loss, profit and overall loss
Find - Quantity sold at 8% loss
Solution - Let the quantity of rice sold at loss be x. So, the quantity of rice sold at profit will be (44-x).
Now, forming the relation as -
Quantity of loss*loss% + Quantity at profit*profit% = total quantity*total loss%
Keep the values in formula
x*(-8) + (44-x)*14 = -44*4
-8x + 616 - 14x = -176
616 + 176 = 14x + 8x
792 = 22x
x = 792/22
x = 36
Hence, 36 kg rice was sold at 8% loss.
